ICH8/ICH9—NVM Information Guide
Notes:
1. SW = Software: This is access from the network configuration tools and drivers.
2. PXE = PXE Boot Agent: This is access from the PXE Option ROM code in BIOS.
3. HW-Shared = Hardware - Shared: This is read on when the Shared Configuration is reset.
4. HW-PCI = Hardware - PCI: This is read when the PCI Configuration is reset.
5. HW-PCIm = Hardware - PCIm: This is read when the PCIm Configuration is reset.
1.4.1 Ethernet Individual Address (Words 00h - 02h)
The Ethernet Individual Address (IA) is a six-byte field that must be unique for each
adapter card or LOM and unique for each copy of the NVM image. The first three bytes
are vendor specific. (For example, these bytes equal 00 AA 00 or 00 A0 C9 for Intel
products.) The last three bytes must be unique for each copy of the NVM. OEM versions
of the product might be required to have non-Intel ID’s in the first three byte positions.
The value from this field is loaded into the Receive Address Register 0 (RAL0/RAH0).
The Intel default is listed in Table 2 .
Note: The Ethernet IA is byte swapped, as listed in Table 2 .
The IA bytes read from the NVM are used by the ICH8/ICH9 until an IA Setup
command is issued by software. The IA defined by the IA Setup command overrides the
IA read from the NVM.
